OpenClovis and RadiSys Partner to Deliver Pre-Integrated, High Availability ATCA Solutions for Telecom Equipment Manufacturers

SANTA CLARA, Calif., ATCA Summit 2006 - October 18, 2006 - RadiSys Corporation (NASDAQ:RSYS), and OpenClovis, Inc., today announced a partnership whereby RadiSys will resell and support OpenClovis high availability middleware and application development tools with its Promentum™ Advanced Telecom Computing Architecture (ATCA) platforms. The pre-integrated solution offered by RadiSys provides telecommunications equipment manufacturers (TEMs) with a single source for all their high availability ATCA requirements and is available today.

“The OpenClovis Application Service Platform and Integrated Development Environment help network equipment vendors quickly and cost-effectively build platform manageability and high availability into their next generation communication products,” said Scott Grout, RadiSys president and CEO. “RadiSys ATCA platforms pre-integrated with OpenClovis software enables equipment providers to focus their resources on building high-value differentiated applications rather than spending precious resources developing basic protocols and platform management solutions themselves.”

The OpenClovis Application Service Platform (ASP) provides a complete off-the-shelf, standards aligned, manageability and high availability software solution. It is operating system- (OS) and platform-agnostic, and is pre-integrated with various distributions of Linux including MontaVista, Wind River and Red Hat. The integrated RadiSys/OpenClovis solution is suitable for a wide range of carrier grade network elements and its usage ranges from application servers, RNC/BSC, media gateway, Security gateway, IPTV, 3G/WiMAX and IMS core elements.

“The combination of RadiSys Promentum platforms and OpenClovis ASP middleware gives the communications industry the flexibility and carrier grade functionality it demands to deliver new value add services and products in a fraction of the time and cost it took on traditional platforms,” said V.K. Budhraja, CEO, OpenClovis. “By together providing fully integrated high value standards-based solutions, we can help equipment manufacturers reduce overall development time and significantly reduce development, lifecycle and equipment costs.”

The RadiSys Promentum product family includes a fully integrated, application-ready platform and modular building blocks designed to address high speed I/O and bandwidth intensive traffic-bearing applications. RadiSys' ATCA strategy delivers a common platform for network element and data plane applications, implemented in a flexible and reliable architecture complete with comprehensive system management.
